Specification of Letters Patent. i

Patented Aug. 11, 190e.`

Application filed September 7, 1904, Serial No. 223,659. Renewed March22, 1907. Serial No.363,956.

To all whom it 'may concern:

Be it known that I, JAMES lLxYs ALLIN, a i citizen of the United States,residing at East j Chattanooga, in the county of Hamilton and State ofTennessee, have invented new and useful Improvements in lTu t-Locks, ofwhich the following is a specification, reference being had toaccompanying drawing asa part thereof, illust-rating said locking meansapplied to four bolt joints used in forming one strong connection, withcross section X of This invention relates to said lockingmeans with itsprimary object to provide said means, which preferably consists of asimple locking pin and socket therefor, light, simple and cheap; of easyand quick manipulation; applicable to devices after theparts have beenolted or clamped together and hence to all commercial joints, bolts andnuts; and to dispense with the necessity of double nutting for suchlocking purposes. Hence it will be observed, that, the invention isapplicable to a screw having a suitable head, to ascrew shaped bolthaving but one head, to either head of a bolt provided with a pair ofclamping heads with one or both of said heads r-eating the clampinglength of said bolt, to a lurality of nuts used successively on the sameolt, with provisionforlocking means between said nuts, to clamping boltwashers, especially to washers for use in wooden joints, and, indeed, toretaining and clamping devices in general.

Referring to the drawing or figure, which is a plain'side elevation withcnil section X taken at X-X, numerals l, 2, 3 and 4, each successivelyindicates a bolt-joint and locking means therefor: with said lockingmeans consisting of a locking groove, 5, as in lock 1, converted into alocking socket 6, as in locks 2, 3, and 4, by turning the bolt-head ornut T, across the central portion of groove 5, adapted thereafter toreceive and carry a locking iin, preferably a small commercial wire nail8, with automatic curving effect upon said pin at its projecting endswhich come in close contact with the sides of the vnut said pin entersand projects from said socket, as in lock 3 or 4, for lockingly engagingthefrictional arts or'members which form and carry sai( socket. Afterthe joint has been ,properly clamped and locked the projecting end ofthe locking pin may then e bent down out of the way upon the face of jthe underlying slotted member. i Said bolt head or nut 7, frictionallypresses the adjoining washer 9, or plate 10, in its rotary clamping andunclamping action; therefore the ends of the locking groove should lieentirely within the extreme circuit of the nut, in order toautomatically bend the pin into direct and fixed locking engagement withthe nut, and as indicated 'by the dotted circle 11.

Dotted line 11 represents the fric'tional circuit of the bolt head ornut. Any frictional 'member of the bolt joint may carry the lockinggroove; but preferably, the locking roove should lieto ,one side of andfree from t 1e nut or clamping head of the bolt when said nut or head isturned sidewise to the groove as illustrated in lock 1- The locking pinS, is forced endwise into said socket with curved, anti rattle, securelocking effect against both the clamping and uli lamping action of saidnut 7. This arrangen entjallows the joint to be quickly unlocked byusingthesaid companion frictional parts asa" air of pliers to cut oil eitherend of the locking pin, also illusvtrated in lock 1, which may be donein heavy j oints by means of strong long handled wrenches, such as arein common usel for bolting railroad rails together; This arrangementallows the remainder of the nail-to drop out as the groove is uncoveredby the turning of the nut; or said locking pin may be withdrawn withclaws, as with a claw-hammer.

'lhe deep groove with its sharp quick bend vor curve outwardlv at itsend close to the nut" not only imparts the desired locking shape to thepin as it enters but also firmly sustains said pin in its place in use;either end being sutlicient in itself to shape and sustain itsrespcctive end of the iin.

Common or usua means for preventimJr the boltJ itself from turning inthe clamped parts of the joint may be employed wien used supplementaryto the locking means herein set forth.

Having thus fully described my invention,

what I claim as new and desire to secure by Let-ters Patent of theUnited States, is:

v1. In an'automatic nut or bolt lock, the combination with an angularclamping member having a smooth under surface, of an underlying partforming a seat for said member and provided with a groove-like socketconstructed and arranged with reference to said member so as to becrossed by a corner of said member when the latter is in a lockingposition, and having an outwardly turne ...H- ........1... ...Nr.HW' .W

` end closely adjacent to a side of said member whereby said member isautomatically locked by driving said pm endwise and without manuallybending the pm, the pin being ing mth said adjacent side of said member,

automaticallybent, retained and supported by the end of the socket.

2. In an automatic nut or bolt lock, the combination with an angularclamping member having a smooth under surface` of an undei-lying partforming a seat therefor and provided with a groove-like socketconstructed and arranged with reference to said member so as to becrossed by a corner of said member when the latter is in lockingposition, and having outwardly turned ends closely adjacent to oppositesides of4 said member in such locking position, and a bendablelocking-pin adapted to be driven endwise into said socket and to beautomatically bent by the latter into its final locking shape andcont-acting with opposite sides of said member, whereby said member isautomatically locked by driving said )in endwise and without manuallybending tie pin, the pin being automatically bent, retained andsupported by the end of the socket.

3. In an automatic nut or bolt lock, the combination ith an angularclamping member having a smooth under surface and with a benda-ble pinas means for locking the same, of a seat forming part underlying saidmember with a straight groove-like socket paraliel with one of the sidesof said member when the latter is `urned sidewise thereto and arrangedto be crossed by a corner of said member in its locking position, saidsocket being constructed with an outwardly turned end closely adjacentto one of the sides of said member and adapted to form a pin bending,

retaining and supporting surface opposed to said side, whereby the pinis automatically bent into contact with such side and retained andsuported in contact therewith. by the end of It e socket.

4. In-an autematic nut or bolt lock, the combination with an angularclamping member having a smooth under surface and with a bendable pin asmeans for locking the same, of a seat forming part underlying saidmember and provided with a straight groove-like socket parallel ith andexternal to one of the sides of said member when said member is turnedside-wise thereto and arranged to be rossed by a corner of said memberin its locking position. said socket being constructed with outwardlyturned ends which are exposed closely adjacent to opposite sides of saidcorner in such locking position and which are adapted to automaticallybend the pin into contact with said sides and to also turned adjacent tothe opposite sides whic l.

form said corner, whereby said socket is adapted to automaticall bendsaid pin into contact with said sides w ien thc pin is driven lengthwiseinto said socket, said pin being automaticallyv bent, retained andsupported against said sides of said member by the ends of. said socket.y

6. In an automatic nut or bolt lock, the combination of a nut and aboltand member clamped thereby and a bendable locking pin centrallyunderlying a corner portion of the face of saidnut and automaticallybent, retained and supported against the side of the nut, said memberclamped being provided with means forv receiving and automaticallybending said pin into such locking engagements when the pin is forcedendwise beneath said nut and made to project outwardly to the side ofthe nut.

7. An article of manufacture, for combination with a nur and a bolt anda bendable locking pin in an automatic nut. or bolt lock, comprising adevice provided with a socket for said bolt and also provided with aslot in the face thereof for and adapted cross-sectionally to whollycarry the said locking pin and lying near and transversely disposed tosaid socket, said slot bein(r abruptl turned outwardly at the end an(adapter to centrally underly a corner portion of the face of the nutwith said end )rejecting and terminating close to the si( e of the nutwhen in clamped locking relations thereto and thus adapted toautomatically bend, retain and support the locking pin againstthe sideof the nut when the pin is forced cndwise into and through said slot.

S. In an automatic nut or bolt-lock, the combination, with a lult and abolt, of a member clamped thereby and provided with a slot centrallyunderlying a corner portion of the face of said nut and a bendablelocking pin inserted endwise into and projecting from said underlyingslot and automatically bent thereby into locking relations with said nutand also su )ported in said locking relations by the end of said slot.

In testimony whereof I allix mysignature,

in presence of two witnesses. Y
